Benzoyl chloride, 3-nitro- → Phthalimidine

Participants

Reaction Steps

To a solution of 4-hydroxy isoindolinone 27 (0.100 gm, 0.67 mmol) in methylene chloride (5 ml) and triethylamine (0.2 ml), was added m-nitrobenzoyl chloride (0.125 gm, 0.67 mmol) at 0° C., and the reaction mixture was stirred at room temperature for 5 hr. After the usual workup, the resulting residue was purified by PTLC plate (solvent was 10% methanol-methylene chloride) to give 2,3-dihydro-1H-isoindol-1-one 32 (0.025 mg, 28%).
